Acoustic Waves in Saturated Sediments

This paper discusses a phenomenological model that describes the propagation of sound waves in saturated sediments. The compressibility and shearing stiffness of the skeletal frame, the compressibility of the fluid, and two major sources of attenuation are included in the model. Attenuation is attributed to two fundamentally different types of energy loss, one resulting from inelasticity of the skeletal frame and the other due to motion of the pore fluid relative to the frame, with each significant in a different frequency range.
